The minor gauge coil outputs differ in that only one of the
coils in each movement is driven by the IC. The other is
driven directly by the analog supply voltage, specifically
onehalf of this voltage. The common output assures that
this is true. By varying the voltage across the other coil to a
greater voltage, the pointer can be deflected more than 45
°
to each side of the externally driven coil. This relationship
is shown in Figure 4.
Note: There are actually eight segments, but only the are
shown here for simplicity.

To drive a gauge’s pointer to a particular angle, the
microcontroller sends a 12 bit digital word to the CS4122.
These 12 bits are divided as shown in Figure 6. However,
from a software programmer’s viewpoint, a 360
° circle is
divided into 1024 equal parts of 0.35
° each and a 112.2° arc
is divided into 256 parts of 0.44
° each. Table 1 shows the
data associated with the 45
° divisions of the 360° driver.
Table 2 shows the data for the center and end points of the
112.2
° drivers. Setting the address to “11” disables all
outputs.
